Gu-nam is a cab driver in Yanji City who leads a pitiful life. His wife went to Korea to earn some money 6 months ago, but he hasn't heard from her since. He plays mah-jong to make some extra cash, but his life only becomes more complicated and pathetic. One day he meets a hitman named Myun-ga and receives a proposal to turn his life around by repaying his debt, an dreuniting with his wife. All for a price of one hit.

Gu-nam crosses the yellow sea and arrives in Seoul. He prepares for his deed and looks for his wife. However, just before he gets to make his move, his target is murdered right in front of him and he is framed for the killing. Although Gu-nam manages to flee the scene, the police are on his tail. Not only that, the person who ordered the hit is attempting to wipe out all evidence of the crime by eliminating gu-nam as well as Myun-ga in Yanji City. Now Gu-nam is on the run for the murder he did not commit and chased by those responsible for this mess.
